There are a number of mechanisms in place at airports, as well as at Transport Canada and within the airlines.
How the slots are allocated, I believe, is mostly right now a matter of negotiation between the airports and the airlines. The minister, with Bill C-52, is only going to get the power to ask what's going on. Involving Transport Canada more in that negotiation would probably assist.
A rationalization of where competition law can say something about those arrangements is going to help. I see the Competition Bureau taking baby steps towards inserting itself in the airline industry's regulation from a competition point of view, and, hopefully, it will eventually be four parties talking about such things as slots.
However, for the moment it's really only two. Because it's a dominant carrier and an established airline, as I said, it goes on the “use it or lose it” rule. If Air Canada wants it back, and it has been using it, it gets it back.
